Hoping someone can help. For the past 5 years my son has been talking to an imaginery friend. At first I asked him who he is talking to and he just kept saying to myself. Then 3 months after him talking to himself he started talking about an imaginery friend. Not to us but to himself. Like for example he would say come and sit over here and are you listening to me. He would also ask questions to this imaginery friend of his and wait for a reply and answer his questions as well. Hope that makes sense. Anyway about 1 year ago he got up in the night to go toilet. Usually he gets up and goes on his own but this time he called for me to take him. So I did and he insisted on me waiting outside for him. Very unlike him as passage light was on. As he came out he said to me mind my friend standing by the door. Completely spooked me out but put him back to bed. As I left to go to bed I could hear him again talking and answering to this imaginery friend of his. Then 6 months after that he was upstairs in his room playing. Daughter was playing in her room and my son told her to play with him in his room. As I went upstairs to put away some clothes my daughter said to me that my son told her about his new friend. My son then stood up and said to me look mummy he is there behind you looking at you. I said that no-one was there. That night my daughter went toilet and as I put her back to bed she turned to the top of the stairs and said look mummy xxxx friend is there. tell him to go away. Any advice please.
